Heat 1 tbsp of the olive oil in a large skillet over medium-high heat. Add the sausage in an even layer. Cook for 2 minutes per side, or until browned. Remove the sausage from the skillet and set aside.
Add the chicken to the skillet along with the salt and pepper. Cook for 4-5 minutes, stirring occasionally, until browned.
Add the remaining tbsp of olive oil to the skillet along with the onion and bell pepper. Sauté for 2-3 minutes until the onion softens and begins to turn translucent.
Stir the garlic and tomato paste in with the veggies. Cook for 1 minute, then add the rice and stir well. Let the rice toast for 1-2 minutes, stirring often.
Add the chicken and sausage back to the skillet along with the paprika, garlic powder, onion powder, Italian seasoning, red pepper flakes, fire roasted tomatoes, and chicken broth. Stir well to combine.
Bring the mixture to a boil, then cover with a lid and reduce the heat to a simmer. Cook for 20-25 minutes until the rice is tender, stirring the mixture and scraping the bottom of the skillet every 5 minutes or so.
Taste for seasoning and add salt & pepper as needed. Garnish with green onion and serve.
